Running Plan Review Runner's World Break 4:15 Marathon Training Plan

Does it build you up smartly?

Mostly, yes: this plan builds in stages. The point it gives up is in the explaining: the phase names change, but nothing tells you what each phase is for, or why the work shifts when it does.

Shifting the emphasis as the race gets closer tends to beat holding the same training for months, though the edge is small. Here the first 5 weeks lean on Wednesday's repeats and a long run that grows. From week 6, tempo running joins some of the Sundays, which is the plan's turn toward the steady work the race itself asks for. That's a sensible arc, with everything rising toward week 13.

Wednesday is the constant. A speed session of quarter, half and full-mile repeats appears in week 1 and every week after it, through race week. What grows is the size of things: longer Sundays, more miles, bigger Wednesdays.

Each hard session does come with a short note on what it's for, so you always know why you're out there. The hill Fridays are the one loose end, with a distance and a hilly route and the rest left open.

Does it protect you from injury?

The build is careful, and the gap is in what happens when something starts to hurt. The plan's only caution is a reminder, in the note on speed sessions, not to overdo it. Nothing describes which aches matter, when a run should become a rest day, or how to come back after one.

That leaves the early warning to you. Many coaches treat a lingering, low-grade ache as the first sign of trouble, though the link to a full injury has so far been measured in footballers rather than runners. Runners themselves tend to describe injury as a sliding scale, from running smoothly through small symptoms to a full stop. One recreational runner told researchers studying running injuries how a nagging ache, or niggle, changes: "If it happens again the next week, and the next week, it doesn’t become a niggle anymore, it becomes a problem where you know it is not going to go away." The time to ease off is early, while the ache is still small.

No strength work appears on the calendar either. Choosing the days and building the sessions falls to you. That's a real gap, because strength training cuts sport injury risk, and by more than stretching or balance work.

The rest of the protection holds up. Compared with the few weeks before it, no week comes as a shock. Hard sessions never land on consecutive days, and the rest days are defined: a day off, with light mobility or an easy yoga class if you want one. Every speed session opens with 2 easy miles and closes with a cool-down.

Lighter weeks come often enough, too. Weeks 2, 4 and 6 each dip a little, and weeks 8 and 12 dip further. That matters on a printed plan, because training that builds without relief tends to raise the risk of injury and illness, and a scheduled lighter week is the simplest relief there is. But the hard work stays in them. Weeks 8 and 12 still carry 4 and 6 miles of tempo on Sunday, so the miles fall more than the effort does.

The steepest steps come in weeks 3, 5, 7 and 11, when you run about a fifth more than the week before. Your aerobic fitness tends to catch up with new mileage within weeks, but tendons and bone usually take longer, from weeks to a few months, so those are the weeks when a small ache deserves the most attention.

What happens when you miss a day?

Some, through its optional runs, but not when something goes wrong.

The optional runs give the plan real give. You can skip them or swap them for cross-training, and in a tired week you can drop to the 4 runs the week is built around and still keep its shape. Mack Baker, a New York runner who reviewed the magazine's Break 4:00 plan, liked that it "allowed me to shift around runs if I knew I had certain days that would be brutal." The easy runs come with a plain check: if you're huffing and puffing, you're going too fast. The long runs come with a softer one: start slower than you think you need to, and don't get tied to your watch. The tempo stretches have an effort scale. All of that lets you run by feel when the numbers don't fit the day.

But that's where the help ends. Beyond the optional runs, the plan never says which sessions matter most. Nothing covers a missed long run, a week with a cold, or a week lost to travel. Whether to make it up or let it go is your call, with nothing to guide it. FIRST co-founder Bill Pierce gave runners one firm rule: "You can't make up what you missed," and you "certainly shouldn't double up on your workouts to catch up with your program."

The Wednesday sessions are the hardest case. They come as paces only, with no effort to fall back on, and those paces come from the goal, not from where your fitness is today. On a Wednesday when the printed numbers are simply out of reach, the plan doesn't say whether to slow down, cut the session short or stop.

Will it get you ready for race day?

Two things sit at the heart of most marathon training. One is the long run, and coaches build the whole week around it. The early evidence ties longer long runs to faster finishes, though no study has tested whether shorter, faster work could do the same job. The other is steady running faster than race pace. For most runners, marathon pace sits well below threshold, the effort you could race for about an hour, so tempo running and race pace are different kinds of training, and neither has been shown to beat the other.

This plan builds both. The long runs climb to 22 miles, three weeks before the race, and if you run every option, your biggest week reaches 47 miles, right for the goal. A study of Rotterdam marathoners led by Tryntsje Fokkema found it "does not seem necessary to include an endurance run of more than 35 km," about 22 miles, which is right where this plan's longest run tops out. On the Sundays in between, a tempo stretch sits in the middle of a shorter run, a little faster than race pace, and it grows as the weeks go on. That's harder running done on legs that already have miles in them, and the last hour of a marathon asks for the same thing.

But the taper is the weak spot. With the 5K tune-up race in week 14, running drops by about a third after the biggest week, then holds nearly level for 2 weeks before falling away in race week. Then the Wednesday of week 15, 8 half-mile repeats, is one of the longest Wednesdays in the plan, 11 days before the race. Cutting back over the final 1 to 3 weeks beats holding training steady on race day, and this plan does cut back. But most of the cut is left to the final week. In the training logs of more than 158,000 marathoners, two Dublin researchers found that a strict three-week taper was linked to finishing about 5 and a half minutes faster than a minimal one. They saw "an opportunity for many recreational runners to improve their marathon performance by simply switching to this more disciplined taper format."

Are the workouts varied enough?

Yes, mostly. The plan mixes several kinds of running, though it leaves out the short, fast kind.

Most of your miles should be easy, because easy running is the base the rest of the week is built on. On top of that, a mix of clearly hard sessions tends to build endurance a little better than steady, medium efforts.

Here the balance is sound. About 4 of every 5 miles are easy. The Wednesday sessions change shape almost every week, from sets of quarter or half miles to 5 one-mile repeats in week 13. Sundays swing between long and easy and shorter with tempo. Some Fridays put you on hills, which the plan uses to build leg and lung power.

But there's nothing short and fast. No strides, no hill sprints, no drills. The hill days are a run over whatever hills you can find, with no set efforts, rather than short, fast climbs. Strides, a handful of 15 or 20 second pickups at the end of an easy run, are a small habit. Short, explosive efforts can make running more efficient, even if strides on their own have not been studied directly.
